“Officially day 1 of the 2018 NFL season today.. and today is officially my first day back running,” Watson wrote.

Watson’s injury was a crushing blow in Houston. He was off to a remarkable start, throwing for 1,597 yards with 18 touchdowns and seven interceptions with a 63 percent completion percentage in six starts after taking over for Tom Savage early in the season. The Texans finished the season on a 1-8 skid after his injury.

If he and three-time NFL defensive player of the year J.J. Watt can both return to form next season, there’s reason for excitement in Houston.
